The cruise control could become dangerous when an affected car accelerates under cruise control, like when trying to climb up a hill, Fiat Chrysler officials told CNN. This could cause the car to become locked in cruise control, and the driver might not be able to tap the breaks or hit the designated switch to turn it off.

One incident related to this issue has been reported to Fiat Chrysler, but there have been no reported injuries.

Affected car owners are told to stop using the cruise control function immediately until the vehicle can be repaired, the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) stated in a press release.

If this issue happens while driving, the NHTSA said drivers might be able to stop the vehicle by pushing the break pedal and placing the vehicle in park once it is stopped. Drivers could also shift the transmission to neutral or forcefully apply the manual break and place the car in park once it has stopped.

Fiat Chrysler officials are asking owners of the recalled vehicles to bring them to a dealership for a software update.
